LIQUID GUN.

Application led July 18,

The invention relates to liquid guns and has for one of its objects to so construct the gun that it may be cheapl manufactured and assembled.' Another o ject is to construct the trig er so that it may be easily connected to te liquid barrel of the gun andalso engaged with the power storing spring of the gun. A further object is to so construct the frame that it will form the false barrel and handle of the gun and provide for Ien aging the tri ger withv the handle in suc away that t e trigger will be normally held from disengagement from the handle. With these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 isa perspective view of the gun embodying my invention;

Figure 2 is a longitudinal section therethrough;

Figure 3 is a perspective view of the frame of the gun;

Fi re 4 is a perspective viewl of the assemb y, including the liquid barrel, piston and trigger of the gun;

Figure 5 is a cross section on the line 5-5 of Figure 2. i

The gun has the frame 1 which is formed of sheet metal folded to produce the false barrel 2 and the handle 3 with the fold at the top of the false barrel. The false barrel has an open front end and a closed hemisphericall rear end, the latter being secured by forming ores in the sheet metal before folding and) then closing these gores at the time of fo ding. The portions of sheet metal on o posite sides of the fold line are alike, each liaving a flange 4 de ending from the front end portion of the fa se barrel and spaced from t e other flange and the transverse flanges 5, 6 and 7, respectively, at the front rear and bottom of the handle 3, the corresponding transverse flanges meeting at their edges. 8 are corres nding terminal flanges extending from t e bottom transverse flanges and ri idly -secured to each other as by spot weldlng. The front transverse flanges 5 have corresponding notches 9 in their edges forming an openin for receiving the trigger of the gun. Tie frame being formed in this manner may be economically manufactured.

iciently far apart to 1927. Serial No. 206,637.

10 is the reciprocable liquid barrel telesco ically engaging within the false barrel an havlng an open rear end and a closed front end formed with the restricted aperture 11. 12 is the trigger which is formed of wire bent to shape. This trigger has at Aby a swaging operation and is forced betweenthe front transverse flanges to occupy a position in rear thereof. By reason of the front transverse flanges having their edges held in contact by the resilience of' the metal, these flanges ma be spread sufrovi e for the insertion of the shouldere portion of the trigger, but will eiectively hold the shouldered portion from accidental disengagement.

17 is the piston having the head'18 slidable within the liquid barrel 10 and the wire shank 19 which extends longitudinally within the .false barrel and has its rear end abutting the rear hemi-spherical end of the false barrel and centered thereby. 20 is a power storing coil spring encircling the shank 19 and having its front end portion engaging under the hook 13 of the trigger and its rear end abutting the collar 21. This collar encircles the shank 19 and abuts the shoulder 22 formed upon the shank preterably by a swaging operation.

With this construction, the piston, the li uid barrel, the trig er, the power storin coil spring and the co lar may be assemble as a unit and then placed in the frame to complete the gun. By having the coil spring engaging the hook of the tri ger assembly of the parts is facilitated an in the completed gun the liquid barrel and trig ger will normali be held in their forward positions determined by the shoulder 16 of the trigger in contact with the front transverse anges 5 of the handle. Furthermore, the strength of the coil spring and the normal position of the trigger and liquid barrel may be readily varied by swaging the piston shank and the trigger to form the shoulders 22 and 16 at the desired points.

What I claim as my invention is:

1. In a gun, the combination of a, frame, areciprocable liquid barrel guided by said frame, a stationary piston cooperating with said barrel, a trigger connected to said barrel for moving the same in one direction, and a spring connected to said trigger adjacent the point of connection of said trigger to said barrel for moving said barrel in the opposite direction.

2. In a n, the combination of a frame, a reciprocaxblle liquid barrel upon said frame, a stationary piston cooperating withsaid barrel, a trigger having a barrel connecting ortion extending through a wall of said arrel, and a spring engagino said barrel connecting portion of the trigger for moving said barrel in one direction.

3. In a gun, the combination of a frame, a reciprocable barrel upon said frame, a stationarypiston cooperating with said barrel, and a trigger for moving said barrel in one direction, said trigger having a hook exi tending through a wall of said barrel and a spring engaging said hook and connected to said piston for moving said barrel in the opposite direction and holding said piston stationary relative to said frame.

4. In a gun, the combination of a frame, a reciprocable barrel upon said frame, a stationary piston cooperating with said harrel and having a shank abutting said frame, a collar upon saidshank, a tri ger having a hook extending through a wall of said barrel for moving said barrel in one direction and a coil spring encircling said trigger shank and having portions engaging said hook'and collar to move said barrel in the opposite direction and hold said piston sta tionary relative to said fra-me.

5. In a gun, the combination of a frame havin a false barrel, a reciprocable barrel sli'dab y engaging said false barrel, a stationary piston cooperating with said reciprocable barrel and provided with a shank abutting the end of said false barrel, said shank being formed with a shoulder intermediate its ends, a collar encircling said shank and abutting said shoulder, a trigger having a hook extending through a wall of said re ciprocable barrel for moving the same in one direction, and a coil spring encirclincr said shank and engaging said hook and col lar to move'said reciprocable barrel in the opposite direction and hold said piston stationary relative to said false barrel.

6. In a. gun, the combination of a sheet metal frame forming a false barrel with a closed hemi-spherical rear end, a reciprocable liquid barrel slidably engaging said false barrel, a piston having a. head within said liquid barrel, and a shank engaging the bami-spherical rear end of said false barrel, said shank being provided with a shoulder intermediate its ends, a collar encircling said shank and abutting said shoulder, a trigger having 'a barrel securing portion extending through a wall of said liquid barrel, and a coil spring encircling said shank and engaging said barrel securing portion of the trigger and said collar.

7. In a un, the combination of a folded sheet metalgframe forming a false barrel and handle, said handle having front transverse flanges meeting at their edges, a reciprocable liquid barrel slidably engaging said false barrel, astationary piston cooperating with said liquid barrel, a wire tri ger having a hook extending through a wal of said li uid barrel for connecting said liquid barre to said trigger, and a shouldered portion insertable between said front flanges of said handle whereby the shoulder normally holds said trigger from disengagement from said handle, and a spring forl ieldably holding said trigger in a position etermined by the shoulder contacting with said front flanges.

In testimony whereof I aiiix my signature.
